Betrayal at Bogwater
This fantasy role-playing adventure is set in the Lake District, a region of fertile farmland and rich mineral resources ruled by the Invincible Overlord. Mountain dwarves mine gold at Thormar’s Peak, nagas pursue intellectual studies, and humans and shirelings work the soil. The boxed set includes an adventure, a Lake District guidebook, a full-color poster map, and a parchment players’ map. The guidebook covers the region’s terrain, climate, history, religions, settlements, trade, institutions, creatures, military units, notable people, and a new player character class. Designed for 4–6 characters of levels 3–4.
